THE SECURITY MINE,


The careful development of the mines of this
State. and in fact of the great Southwest has been
productive of the best resnlts and in many in
stances far better than even the sanguine owners
have dared hope for.
Perhaps one of the most remarkable instances of
the great change which has been accomplished 10 In
the Security mine at Silver Cliff. During the early
days of Silver Cliff there taken from this prop
erty orc many thousand dollars in value from o
small pocket, but after this the owners seemed TO
loso the vein and were unable to discover 1T, al
though prospecting was doue at numerous points.
bnt being merely surface workings, failed to make
any important discovery. AbOat January 1st tho
security COMPANY engaged the s Ts, OF u a.
men who have had many years experience in tho
Western mines, and also men who had good prac-
tcal knowledge OF different bodies OF ore and their
various forms. After careful examination OF
the property, Mr.. &. II. johnson, tue manager, de-
cded to proceed IN rather a remarkable manner to
svsp IT, M On ds SV tine
face Of tho hill and developing by series OF
shelves This mineral hill is capped with porphyry
for depth of forty or fifty feet This rock gener-
ally has but little valuable mineral in it. yet some
veins were foand which carried good ore, but the
greater portion Of this cap 10 waste and has to be
removed. The next lower shelf Is about twenty
feet thick and has vast body of ore which will
average about twenty-five ounces The next bench
il about forty feet thick and In this has been found
some fine ORE which in many instan res will run
several hundred dollars to the ton, and in one in
stance the ore assayed as high as $685. per ton.
This was u remarkable yield for this character OF
ore In this manner, tho snme as any stone quarry
10 worked, has Mr. Johnson gone on with the de-
vcopment ard is now taking out every day very
large amount of pay ore.
The mill is one of the most perfect and complete
mills We have ever seen. Great care seems TO nave
been taken with 1t in every part 1t is 12O by 100
feet, with an elevation of ninety feet. The mill
contains forty stamps, all fitted with sef-feedors
two Blake crushers, six revolving screens twenty
four lIartZ jigs three four-cOmpartmeut Iigs, one
Golden Gate concentration table two Fruo yanners
ten Triumph coucentrators and all the modern ap-
planes necessary to maks the perfect mill. This
machinery is driven by a 25O-horso power Corllss
engine and all works In perfect order.
Tbs mill began to run on June 1st and has run
$50 tons of concentrates which will average about
sixty ounces. There are now on the dump about
$1,000 tons of ore " hich will give an average OF
$l7 so per ton. There is also in the storehouse Of
the ny per veins which will average about $500 per
ton. The mine employs seventy-tve mon and is be-
ing orked in TIE most perfect manner On June
9Th the average product OF the jigs was sxty-eght
o1nces. and OF the concentration tables one hundred
ounces. On Juno 9th n very rich vein OF ore was
struck which carried native silver. This was en-
tirely peced and is all the moro valuable as 1t
but confirms tue fact that the cnurhe Of develop
ment followed by Mr. Johnson is the proper one for
this vast mineral body. No assay had Mt that time
been made of this ore. but it was evidently far
richer than any heretofore found.
After a careful examination of this property. we
cannot imagine how any one can call II swindle
and fraud. and we cannot but believe that some
parties hn have done so have been grossly misled
The careful development which is being done at the
Silver Cliif will awake from tho lethargy in which
she has been for several years and become one or
the great silver producing camps OF the state.
